)* Clean inside surfaces of the air tank thoroughly and remove all condensed liquid after dryer failure.
Once a dryer fault is cleared and after its reassembly, the dryer should quickly be regenerated, best
when using continuous compressor operation at a pressure of around 1 bar for a period of at least
1 hour; then check the dryness of the compressed air.
